Overview

The HJ40x10B and the companion highly telephoto HJ40x14B represent the pinnacle of Canon portable high definition EFP lens design.

These lenses are intended for producers and broadcasters engaged in documentary, natural history, and the many other challenging location productions that seek superb image capture over very considerable distances. These lenses embody superb built-in image stabilization systems that have become industry renowned. Aerial shooting, sports and entertainment coverage, portable acquisition in arduous terrain and under dynamic environmental situations (heavy winds) – are all superbly supported by these stalwart HD lenses.

ABOUT THIS LENS
The HJ40x10B and the companion HJ40x14B are a high definition EFP lens family that brings entirely new shooting flexibilities to field production. The HJ40x10B can extend to 770mm with the extender while the HJ40x14B can achieve an unprecedented 1120mm. Both lenses represent the very best in optical and mechanical design and their unique optical image stabilization systems make possible the capture of rock steady high definition imagery under the most adverse of field conditions.

They represent an excellent marriage of needs for creative flexibility and mobility in a handheld HDTV camera system with the demanding performance requirements for high-end HDTV image acquisition at long focal lengths. The design optimization strategies included a dual lens approach to broaden the shooting options, achievement of an adequate sensitivity, maximization of image contrast, and preservation of the highest MTF over the long focal ranges.

High contrast is ensured by superb control of black reproduction – with optical and mechanical design innovations that substantially reduced flare, veiling glare, and any internal reflections. Similar attention to minimization of ghost images and other highlight-related chromatic distortions caused by strong light sources on-axis and off-axis further extend the operational contrast range of the lens.
